cant believe im actually replying....but

BOV's dont "flutter" the "choof", like a sneeze

That flutter sound is caused by compressor surge, i.e. BOV isnt doing its job of flowing boost when the throttle is shut, and the air pushing its way back into the compressor

You cant try removing ur BOV and blanking it off

yeh, thats not a BOV, they have just blocked off the hole on the intake pipe where the BOV normally sits.

makes the air travel back through the turbo instead of into the atmosphere

the noise is made from the turbo fins chopping up the air and then its pushed out through the pod filter

its not the best for your turbo but prevents intake pressure drop between gear changes

i did this in my 33.... it sounded unreal... scared shitloads of people and just plum sounded tuff.... but it made the thing soooo hard to drive... alright when on the limit... but just cruising, gear changes were made soo much harsher and the shock to the driveline was quite violent when releasing the throttle. it didnt take long for the turbo to shit itself either. afms dont like it much either.

and it was only a weekend car... not a daily.

not a good idea... a good plumb back and metal tubing will make a nice enough sound.

if you do though, it sounds better if you get a hard pipe to the turbo, it will sound better than the rubber one.

cheers

      Unpeeling the Orange

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
